Why is photovoltaic power a green and low-carbon energy source?

Photovoltaic power generation has significant energy, environmental protection, and economic benefits, and is one of the highest quality green energy sources. Under the average sunshine conditions in China, installing a 1 kW distributed photovoltaic system can generate 1200 kWh of electricity per year, reduce the use of coal (standard coal) by about 400 kilograms, and reduce carbon dioxide emissions by about 1 ton. According to research by the World Wildlife Fund (WWF), installing a 1 square meter photovoltaic power generation system is equivalent to planting 100 square meters of trees in terms of reducing carbon dioxide emissions. At present, the development of renewable energy such as photovoltaic power generation will be one of the effective means to fundamentally solve environmental problems such as haze and acid rain.

How to maintain your own photovoltaic power plant in summer?
  1. Maintain ventilation, regularly check the heat dissipation around the inverter to see if the air can circulate normally, regularly clean any obstructions on the components, regularly check if the brackets and component fasteners are loose, and check if cables are exposed.

  2. Ensure that there are no weeds, fallen leaves, or birds around the power station. Remember not to sun crops, clothing, etc. on the photovoltaic module. These obstructions not only affect the power generation, but also cause the thermal spot effect of the module, triggering safety hazards.

  3. It is prohibited to spray water on components during high temperature periods to cool them down. Although this soil method can have a cooling effect, if your power station is not designed and installed with proper waterproof protection, there may be a risk of electric shock. In addition, the operation of watering to cool down is equivalent to an "artificial solar rain", which will also reduce the power generation of the power station.

How to effectively prevent fires for distributed rooftop photovoltaic power plants?

1.Before construction, strictly implement national design standards, standardize design, ensure construction quality, avoid cable false connections, and choose photovoltaic equipment with high reliability and good business reputation; Especially take fire prevention measures for cables: Fire separation and flame-retardant cables should be used as the main measures to deal with cable fires in cable trenches. Cables laid in trenches and trays should choose Class C or above flame-retardant cables.

2. Regularly inspect the working environment of the power station during its operation cycle. Clear the flammable and other debris piled up under the component support, ensuring sufficient space in front, back, left, and right of the component, ensuring air circulation, and achieving the purpose of cooling.

3. Check the heat dissipation of the inverter. Generally speaking, various components in the inverter are prone to generating high temperatures during operation, resulting in a higher overall working environment temperature for the components. Therefore, it is necessary to regularly inspect and do a good job in ventilation of the inverter to ensure air convection.

4. Regularly inspect photovoltaic modules. Is there any hot spot problem, hidden cracks, pollutants blocking, etc.? If any problems are found, handle them promptly.

How to simply increase the power generation of distributed roof components?

The roof photovoltaic modules need to be cleaned regularly. 1. Regularly check the cleanliness of the component surface (once per month), clean it with clean water, and pay attention to the cleanliness of the component surface during cleaning to avoid residual dirt blocking and causing hot spots on the component; 2. In order to avoid electric shock injury and possible damage to the components caused by wiping them under high temperature and strong sunlight, the cleaning time is in the morning and evening without sunlight; 3. Try to ensure that there are no weeds, trees, or buildings that are higher than the components in the east, southeast, south, southwest, or west directions of the components. Trim the weeds and trees that are higher than the components in a timely manner to avoid blocking and affecting the power generation of the components

What are the working conditions of the components and do they still generate electricity at night?

As long as there is light, the component will generate voltage, and the photogenerated current is proportional to the light intensity. Under weak light conditions, the component will also work, but the output power will decrease. Due to weak lighting at night, the power generated by the components is not sufficient to drive the inverter, so the components generally do not generate electricity. However, under extreme conditions such as strong moonlight, photovoltaic systems may still have very low power.

Why is summer the most suitable season for installing photovoltaic power plants?
  1. Summer is the season when households consume a lot of electricity. Installing a home photovoltaic power station can save on electricity costs.

  2. Installing household photovoltaic power plants can enjoy national subsidies and sell excess electricity to the power grid, thereby obtaining sunlight benefits, which can be achieved in one fell swoop.

  3. The photovoltaic power plant laid on the roof has a certain insulation effect, which can reduce the indoor temperature by 3-5 degrees. While the building temperature is regulated, it significantly reduces the energy consumption of air conditioning.

  4. The main factor affecting photovoltaic power generation is sunlight. In summer, the days are long and the nights are short, and the working hours of the power station are longer than usual, resulting in an increase in power generation.
